BOXJ-STAYING MACHINE.

SPECIFICATION forming part of Letters Patent No. 545,808, dated September 3, 1895.

Applioation filed December 1, 1894- Serial 110530 532. on model.)

To, all whom it may concern;

Be it known that I, JULIUS MOHS, a citizen of Germany, residing at Dresden-Altstadt, Germany, have invented certain new and useful Improvements in Box-Staying Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to box-staying machines, and more particularly to that class of box-staying machines in which a strip of paper, linen, or similar sheet material is cut in suitable lengths and pasted on the corners of the box to be stayed, thereby strengthening the same at such corners. p,

The object of my invention is, in the first place, to insure a perfect and accurate feeding of the stay-strip to the point at which it is to be applied to the box and to prevent any tendency of such strip to arrive at the corners of the box out of alignment or in such a position in which it would not lie straight on the corners of the box.

The object of my invention, moreover, is to prevent all tendency of an accumulation of gum or other adhesive matter in the working parts of the machine, whereby the same would become clogged and thrown out of working condition. 3

A further object of my invention is to secure absolute certainty that the strip will be fed into the hammer portion of the head, so that the same can be applied to the corner of the box, which rests upon an anvil below said hammer portion.

With these objects in view a machine embodying my invention comprises, in connection with an anvil, a reciprocating plunger or head on which are mounted and fixed with regard to each other the recessed hammer portion into which the strips as they are cut off are fed, an intermittent strip-feeding device, and a cutting device preferably located between the hammer portion and the stripfeeding device. The strip-feeding device consists,'essentially, of a feed-roller intermittently actuated and the yielding presserframe between which and the feed-roller the Strip is pressed and fed clear. The said the strip as it is fed forward.

My invention, moreover, comprises such features, elements, and combinations of elements as will he hereinafter set forth, and particularly pointed out in the claims.

In the drawings accompanying this specific'ation,-Figure 1 represents a side elevation, partially in section, of a machine embodying my invention; Fig. 2, a front elevation of the same; Fig. 3, a side elevation, viewed from the side opposite to that in Fig. 1, of the reciprocating head of the box-stay machine; Figs. 4 and 5,-rear elevations of the said head, also on an enlarged scale and showing the same occupying two diiferent positions; Fig. 6, a detail view in longitudinal section of a portion of the said head on line 6 6, Figs. 4

and 7; Fig. 7, a detail view of the, shears; Figs. 8 and 9, transverse sections of the stripfeeeding device on lines 8 8 and 9 9, Fig. 3; Figs. 10 and 11, detail views of the strip-applying device, showing the same in two different positions; and Fig. 12, a plan view of the shears together with contiguous parts.

By referring to the drawings it will be noted that the said strip a, which may be of any suitable material-such as paper, linen, and the likeis arranged in a web mounted in a standard 0/ on a frame A of the machine, and is thence conducted over rollers a into contact with a paste-applying roller B, which, as shown, is cut away in part, so as to form annular ribs 1) b, by whichthe paste or other adhesive material is applied to the strip a in longitudinal stripes b, as shown in Fig. 2. The paste or adhesive material, in a liquid or semi liquid condition, is contained in the paste-trough B, which in the present instance is pivoted at b on an arm extending fromlthe standard 19 which supports the rollers b and o The paste is transferred from the fountainroller B which dips into the paste-trough, to the transfer or doctor roller b and thence to the paste-applying roller B. A T or L shaped arm 13 extends downward from the trough and is provided with an adjustable weight 17 as shown, whereby the pressure of the doctor-roller 11 against the paste-applying ICO roller may be regulated at pleasure. The parts thus far described constitute the pasting device. The strip a passes from this pasting device to the reciprocating head 0, which in the present instance is shown as secured to, or forming part of, an arm pivotedat c to the machine-frame. The head is normally held in an upright position by a spring 0, connected at one end to the rearwardly-extending part c of the arm C and atthe other end to themachine-frameA. Atreadle D, fulcrumed at d to the machine-frame and connected with the arm 0 by a link d, serves to depress the said arm and with it the head 0. It is evident that any other means for giving a reciproeating motion to the head 0 may be substituted in lieu of the means just described without departing from my invention. The head 0 comprises the hammer or plunger E, which, in conjunction with the anvil F, rigidly secured to the frame A, serves to apply the severed and pasted strip to the corners of the box. The anvil F, for this purpose, is in the shape of the corner of the box to be acted upon, as shown in Figs. 2, 10, and 11, and the plunger Eis provided with a recess c,-Figs. 4 and 10, also conforming to the shape of the corner of the box. In addition to this recess the plunger is provided with guide-grooves e, (best seen in Figs. 4, 10, and 11,) which hold the strip in the proper position prior to its being applied to the corner of the box.

The strip-feeding device G is best explained in connection with Figs. 1, 3, 4E, and 6. As there shown, the same comprises the parts now to be described: the feeding-roller H, having a toothed, corrugated, or otherwise roughened periphery and journaled in an arm h, extending from the head 0, a presser-frame 1, partially encircling the roller H, pivoted at i to the side of the head and yieldingly held against the feed-roller H by a spring 1;, a ratchet H, connected with the feed-roller, a pawl-lever J, carrying a spring-pawl j and loosely mounted on the journal h of the feedroller H, and the stop K, mounted preferably adjustable, as shown, in the frame A and against which a lug or projection h on the pawl-lever J is adapted to strike at every upward stroke of the head OJ The pawl-lever J is normally held upward by aspringj, and its upward motion is limited by a stop 7' The lug 71 is made adjustable in a slotj on the pawl-lever J, as shown, and is preferably provided with an antifriction-roller j, to reduce friction as much as possible. By making the lug h adjustable, the amount of feed at each upward stroke of the head 0 and hence the length of the strip to be cut off can be regulated to suit various sizes of boxes. The stop K is made adjustable in the frame A by passing its shank 7a through a socket in the said frame and providing a thumb-screw or other suitable equivalent, device for holding it in its various positions of vertical adjustment.

By this means the step can be ac: vcurately adjusted so as to be struck at the proper moment in the upward stroke of the head 0.

The form of the presser frame I in crosssection is best shown in Figs. 8 and 9. As there shown, the same is provided with flanges 2' t to prevent the strip a' from slipping laterally and hencecoming out of proper alignment with relation to the corner of the box on the anvil F, and also with a rib or ribs 11 longitudinally arranged so as not to coincide with or overlap the stripes b b of paste applied to the paper strip a, or, in other words, to bear only against those portions of the strip to which no paste has been applied.

The cutting device L, as shown, is preferably arranged between the strip-feeding device and the plunger E. The same consists of two shear-blades L L pivoted at Z on a bracket forming part of the head 0, and normally held closed by a spring Z, connected with the two rearwardly-extending arms Z Z of the shearblades. Between the two arms Z 1 and onthe head C are pivoted the two cams M M adapted to bear against the arms Z of the shear-blades L L respectively. Connected with these cams is a lug or toe M, which, in connection with the guide or cam rail N, acts to operate the cams, and hence to open and close the shear-blades at each stroke of the head, the guide or cam rail N being, of course,

fixed or rigidly secured to the frame A, as

shown at n, or otherwise held stationary with respect to the frame. The cams M M the toe M, and cam-rail N are so arranged with relation to each other that as the head 0 is elevated the shears are opened into the position indicated in Fig. 5, and as the said head descends the lower shear-blade is first acted upon and moved upward until its outting-edge reaches the horizontal position exactly in line with the lower edge of the strip a, asindicated in Figs. (5 and 7, whereupon it is arrested, and the head continuing to move downward the upper blade L begins to move downward until its cutting-edge overlaps the cuttingedge of the shear-blade L thus severing the length of strip to be applied to the corner of the box. It is essential thatthe lower shear-blade L is arrested entirely after it has once reached its horizontal position,

just bearing against the lower surface of the strip a, as if it should move farther upward it would tend to hold the end of the strip a, after a piece had been cut therefrom, out of alignment with theguide c in the plunger E, and hence interfere with the proper action of the machine.

The operation of the machine thus described is as follows: By pressing treadle D the head 0 is depressed, and by drawing upon the paper strip or causes a suitable length of the same to be unwound from the reel or Web and to be passed forward through the pasteapplying device l3, a the. The toe M moving along the guide or cam rail now causes first the cam M to release the shear-blade L and allow it to move upward until its cutting-edge is in the horizontal position, and then the cam'M to release the other blade L, causing it to descend and cut the strip of paper a against the lower shear-blade L it being assumed, of course, that the end of the strip a has been brought forward into the guidegrooves e of the plunger E. The shear out having thus been made, the further descent of the plungerE, in conjunction with the anvil F, bends, presses, and pastes the length of the paper strip a cut off against the corner of the box. (See Figs. and 11.) The treadle.D being now released, the head 0 rises,releasing the plunger E from the anvil F and permitting another box-corner to be put into position on the anvil for staying; The shear-blades are also opened in this up Ward movement as the toe travels over the cam-railN, and the lug 72 as'it strikes against the stop K, causes the pawl-lever to turn, and through it the wheel H to revolve and to feed the paper strip a, which is clamped between it and the presser-bar I, forward, so as to take up the slack and fit another length of paper into the plunger E. On again depressing the plunger the above operations are repeated, due. 4

The particularly essential feature of my invention is the fact that the feeding device and the plunger are rigidly connected, whereby I obtain the advantage that the strip is fed into the plunger accurately and with certainty, and all liability of these parts to change their relative positions being eliminated there is no danger of the machine getting out of order.

The mounting of the cutting device on the same head with the two last-named organs is also of importance, inasmuch as by so arranging them all liability of these parts to change their relative positions, and hence interfere with the operation of the machine, is obviated.

.My particular feeding device, embracing the feed-roller in connection with the flanged presser-frame partially encircling and yieldingly heldagainst the same, results in an absolutely accurate advance of the paper strip, so that it will occupy the exact position with relation to the corner of the. box to which it is to be stayed.

The particular means for reciprocating the head 0 (shown by way of illustration) is not essential, and any other suitable or convenient means for reciprocating the said head may be substituted in lieu thereof.

Other means than theguides e for supporting the strip below the plunger may also be devised, and in general the machine may be greatly modified without departing from the spirit of my invention.
